Multicentric Study on Oncological Outcomes and Prognostic Factors of Open Partial Horizontal Laryngectomies

: Objective: In recent years, the number of open preservation surgeries for the treatment of laryngeal Cancer has increased. This surgery aims to maintain laryngeal function and ensure oncological radicality, thereby avoiding a total laryngectomy (TL) that could significantly impact the patient's quality of life. The purpose of this study was to assess the oncologic results of OPHL I and II and to identify prognostic factors that could impact patient survival and local failure rates. Methods: This study was conducted on 182 patients with laryngeal squamous cell carcinoma treated with OPHLs between 2005 and 2015. The survival rates of a group of patients treated with TL between 2004 and 2014 were taken into consideration to compare survival outcomes. Results: The disease-specific survival in pT2 and pT3 tumors in relation to the type of surgery showed no statistically significant difference between OPHLs and TL (P = .54 and P = .63, respectively). The 5-year T-recurrence-free survival showed that pT4 tumors, perineural/vascular positive invasion, and OPHL IIb + ARY-treated tumors were associated with a higher risk of tumor recurrence (P < .0001, P = .0005 and P = .016 respectively). Conclusions: OPHLs represent an excellent alternative to TL considering the characteristics of the tumor and the general conditions of the patient.
